Protocols, Smart Polling, and Arc

A list of the improvements for Protocols, Smart Polling and Arc that have been introduced in this release.

  • Removed the chance to assign the type controller to a engineering workstation in a Rockwell network under particular circumstances.
  • Guardian now automatically confirms media access control (MAC) addresses known to Asset Intelligence without the need for any specific communication via passive traffic, making the asset creation process faster.
  • Nozomi Networks Operating System (N2OS) can now passively identify DROP assets for Emerson Ovation installations using the Ovation DDB protocol. The old ovation protocol is now named ovation-ddb. All communications will be managed creating links with the new name. Old links under the ovation name will become inactive and can be managed by the Clean up old inactive links setting in the Garbage Collection section, or deleted manually. The user is recommended to update old queries if applicable.
  • Introduced variables extraction for the Emerson Ovation DDB protocol.
  • Introduced support for the passive detection of operations for Emerson devices.
  • Passive traffic now detects Emerson Ovation controllers.
  • Improved the detection of private addresses for IPV6.
  • VLAN information can now be passively extracted from ERSPAN-II traffic.
  • Improved the robustness of false positives for packet rules for Veritas Network Backup protocol.
  • The Garbage Collector no longer deletes imported nodes, and related assets, if no passive traffic is detected.
  • Introduced support for the detection of Inaba Choco Tei cameras.
  • Improved the passive detection of hardware components for Mitsubishi Electric devices.
  • Introduced support for extended backplanes on Mitsubishi devices. The Extended backplanes are extracted as HW components.
  • Alerting for niagara-fox is now disabled by default. It can be enabled with the configuration probe protocol niagara-fox protocol_validation_header true.
  • Extended the support for turbo capture mode for the fiber network cards on physical appliances.
  • The node merging strategy for All-in-one Central Management Console (CMC)s will return the first high-quality non-blank custom field.
  • Improved the robustness of the import task with respect to empty or invalid entries.
  • Smart Polling no longer tries to poll broadcast addresses.
  • Guardian can now obtain data about BACnet devices in serial networks connected to a BACnet router through Discovery, and enrich such devices by polling them afterwards.
  • Guardian now sets the node's creation time at every execution of Discovery and Smart Polling.
  • ONVIF discovery now recognizes devices responding from any port.
  • Discovery can now obtain more data from Cognex devices.
  • Advantech strategy now extracts CPU and memory usage from the monitored devices.
  • The SNMP strategy for Smart Polling has been enhanced to extract data using LLDP OIDs, enabling for upcoming physical network mapping features.
  • Smart Polling now delivers more accurate hardware module data for Mitsubishi Electric iQ-R devices.
